4.2
MSETCL proposal of shifting of Aurangabad (Waluj) – Pune (PG) 400kV D/C
line from 400kV Aurangabad (Waluj) to 765/400kV Aurangabad (PGCIL).
In the 38th SCM of WR held on 17.07.2015, MSETCL has proposed shifting of
Aurangabad (Waluj) – Pune – PG 400kV D/C line from 400kV Aurangabad (Waluj) to
765/400kV Aurangabad (PGCIL) to remove the constraints for import of power in
Maharashtra control area. The loading on the 2X1500 MVA 765/400 kV ICTs at
Aurangabad (PG) substation and Aurangabad- Aurangabad I (Waluj) 400 kV
interconnection was the limiting factor for import of power in Maharastra from ISTS.
In the meeting, it was agreed that MSETCL proposal of shifting of Aurangabad
(Waluj) – Pune (PG) 400kV D/C line from 400kV Aurangabad (Waluj) to 765/400kV
Aurangabad (PGCIL) would be studied jointly by CEA, CTU, WRLDC and MSETCL.
The peak demand met by Maharastra in August 2015 was 18447 MW. Accordingly,
load flow studies were carried out by taking recent load flow file from WRLDC for a
demand of 18,445 MW in Maharashtra. In the studies intrastate generation of
Maharashtra of 11893.4 MW (Tirora – 2418MW, Koyna – 552.8, Jaigad – 1000MW,
Amravati- 750 MW) and import of about 6500 MW from ISTS has been considered.
The load flow study was carried out to see the impact of the following transmission
schemes which are already under implementation by PGCIL/MSETCL on the power
flows in Aurangabad (Waluj)- Aurangabad(PG) 400 kV interconnection:
(i)
LILO of 400kV D/C lines Parli – Pune (PG) at Pune (GIS) - already
commissioned.
(ii)
LILO of Aurangabad – Pune (PG) at Pune(GIS) ) by September 2015
(iii) 2 nos. of 400 kV bays at Dhule (MSETCL) for termination of Dhule(Sterlite) –
Dhule (MSETCL)400 kV D/C line.
(iv) Aurangabad – Sholapur D/C 765kV line by December 2015
(v)
Aurangabad – Boisar D/C 400 kV line by March 2016
(vi) Aurangabad – Padghe 765 kV D/C line by March 2016
(vii) LILO of one circuit of Aurangabad – Padghe 765 kV S/C line at Pune (GIS) –
project under bidding stage.
4.3
The load flow results are attached as Annexure-3. From the load flow analysis it is
evident that with the commissioning of the above mentioned elements loading on
400kV Aurangabad (Waluj) – Aurangabad (PG) D/C line has been reduced from
2200MW to 640MW and Aurangabad (Waluj) – Aurangabad (PG) D/C line would not
be constraint for import of power to Maharashtra. In view of this, MSETCL proposal
Agenda notes - 39th SCMPSPWR

of Shifting of Aurangabad (Waluj) – Pune (PG) 400kV D/C line from 400kV
Aurangabad (Waluj) to 765/400kV Aurangabad (PGCIL) is not required.
5.0
Additional 400 kV feed to Goa
5.1
In the 38th SCM of WR the following Inter State Transmission System scheme was
proposed:
(i)
(ii)
5.2
5.3
Establishment of 2X500 MVA, 400/200 kV substation at Xeldam and its
interconnection with Narendra (existing) 400 kV substation through 400 kV
D/C line with quad conductor. The interconnection between the existing 220
kV Xeldam substation and the proposed 400/220 kV Xeldam substation could
be through bus extension or through 220 kV interconnecting lines, as the case
may be.
400kV (Quad) connectivity between the new substation at Xeldem and
Mapusa to take care of any N-1-1 contingencies involving outage of any one
400kV infeed to Goa.
In the meeting POWERGRID has suggested the alternative of LILO of NarendraKolhapur 400 kV D/C line (765 kV line to be initially charged at 400 kV level) at the
proposed Xeldam 400 kV substation as 765 kV operation of Narendra-Kolhapur D/C
line was not envisaged in near future and it would increase the utilisation of
Narendra-Kolhapur D/C line. It was decided that the alternative suggested by
POWERGRID would be studied jointly by CEA and CTU and based on its merit the
same would be included in the scheme that would be put in the SR SCM for their
approval.
POWERGRID has further carried out studies and suggested alternatives(One- LILO
of one ckt of Narendra (existing) – Kaiga 400kV D/c line at Xeldem (New) and
Xeldem (New) – Colvale (Mapusa) 400 kV (Quad/HTLS) D/c line, Two- Kolhapur
(PG) – Colvale (Mapusa) 400kV (Quad/HTLS) 2nd D/c line and Colvale (Mapusa) Xeldem (New) 400 kV(Quad/HTLS) D/c line). Although alternative One is better in
terms of power flow, the LILO shall involve construction of more than 100KM line
length in the hilly and forested areas of Western Ghats. About 30% of the area of the
Western Ghats Region is under forests. In the past, during forest clearance process
of Kaiga-Narendra 400 kV line, POWERGRID faced lot of resistance from various
activists and NGOs. The clearance was recommended by Karnataka government in
2002 only after joint confirmation from POWERGRID and CEA during detailed review
that no further transmission line shall be laid in the area. It is therefore apprehended
that LILO of one ckt of Kaiga-Narendra 400 kV D/C line in Western Ghat area shall
be resisted by the activists/NGOs and obtaining forest clearance and actual
implementation of line may be delayed as in case of Mysore-Kozikode 400 kV line
(Mysore –Kutta portion) due to such resistance and possible legal intervention.
Therefore, alternative Two has been suggested by POWERGRID along with
reconductoring of Sholapur (PG) – Kolapur 400kV Double Circuit Line with HTLS
conductor.
The following alternatives for feeding Xeldam 400 kV substation has been studied
including the alternative proposed in the 38th SCM and the alternative proposed by
POWERGRID:

400 kV D/C line at Xeldam with LILO point at
Narendra end.
LILO of one ckt. of Kaiga-Narendra (existing) Option 8
Kaiga end.
The results of the load flow studies conducted for the above mentioned eight alternatives is
enclosed as Annexure - 4. The observations based on analysis of the results are:
(i) Option 1 is technically best possible alternative for providing ISTS feed to Goa
system since it has successfully relieved loading on existing 220kV network as well
as 400kV network which is feeding power to Goa system.
(ii) For implementation of Option 1 two no. of 400 kV bays would be required at
Narendra (existing) 400/220 kV substation. In case of space constraints GIS bay
may be provided. If no space is available then option 6 or option 7 could be
implemented which are equally good as option1.
(iii) In the all the eight alternatives, the 400 kV lines to Mapusa/ Xeldam has to cross
the Western Ghats section.
(iv) In the corridor through which the Narendra(existing)-Xeldam 400 kV D/C line would
pass, there are already existing Ambewadi – Xeldam/Ponda 220 kV D/C line and
Supa-Ponda 110 kV D/C line. Ambewadi – Xeldam/Ponda 220 kV D/C line is
functional whereas the Supa-Ponda 110 kV D/C line is not in use. These lines are
maintained and operated in their respective geographical areas by Goa and
Karnataka respectively. In case of difficulty in getting RoW for implementation of
Narendra (existing)-Xeldam 400 kV D/C line, the RoW of the existing Supa-Ponda
110 kV D/C line could be used.
(v) Option 2 - there will be only a single source for feeding Goa at 400kV level i.e.,
765/400 kV Kolhapur (PG).
(vi) Option5 i.e, LILO of one ckt. of Narendra(New)- Kolhapur(PG) 400 kV D/C line at
Xeldam which was suggested in the 38th SCM is not a suitable alternative as there is
uneven loading on the 400 kV circuits feeding power to Xeldam ( 540 on one ckt and
82 MW on other ckt.) . Also Narendra(New)- Kolhapur(PG) is a 765 kV D/C line
which in present scenario is being operated at 400 kV level and in future when this
line would be operated at 765 kV voltage level , the Xeldam 400 kV along with the
feeding lines also needs to be upgraded to 765 kV level.

Members may deliberate and finalize the second 400 kV feed to Goa so that the
same could be taken up for approval in the SCM of SR.

Connectivity System for Lanco Vidarbha Thermal Power Pvt. Ltd. (LVTPPL)
6.1
In the 21st Meeting of WR constituents regarding Connectivity / Open Access
Applications held on 17.07.2015, the connectivity arrangement agreed earlier (i.e.,
LILO of Seoni - Wardha 765 kV S/C line at LVTPL TPS) for LVTPPL was revised as
below:
(i) LVTPPL TPS Switchyard – Warora Pool 765kV D/c line (to be implemented
through Tariff Base Competitive Bidding route)
In the meeting, M/s LVTPPL was requested to confirm the time frame by which
connectivity line is required so that suitable action may be initiated for
implementation of the line through Tariff Based Competitive Bidding route.
6.2
6.3
M/s LVTPL vide their letter dated 27th August, 2015 has requested for continuation of
the earlier connectivity granted i.e. LILO of Seoni – Wardha 765kV S/c line at
LVTPPL TPS and subsequently a meeting was held in CEA on 2.9.2015 to discuss
the connectivity issue (Minutes enclosed as Annexure- 5). In the meeting M/s
LVTPPL was requested to confirm the following requirements so that the connectivity
line (LVTPPL TPS – Warora Pool 765kV D/c line ) could be included in the agenda
for Empowered Committee for implementation of the scheme through TBCB route.
a.
M/s LTPPL needs to confirm the commissioning schedule of the generation
project
b.
As per CERC sharing regulations, transmission charges are payable by
beneficiaries only after the commercial operation of the generator. Till then, it is
the responsibility of M/s LVTPPL to pay the transmission charges.
c.
M/s LVTPPL need to sign connectivity agreement and submit requisite bank
guarantee.
Response from M/s LVTPPL is awaited. However connectivity of LVTPPL may be
granted through LVTPPL TPS Switchyard – Warora Pool 765kV D/c line. M/s
LVTPPL would be required to sign requisite agreements for taking up the
transmission scheme under Tariff Base Competitive Bidding route.
7.0
Provision of 1x240MVAR line reactor at Pune GIS end for Aurangabad (PG) –
Pune GIS 765kV line (formed after LILO of one ckt of Aurangabad (PG) –
Padghe (PG) 765kV D/c line at Pune GIS - LILO Length Considered - 67KM).
7.1
In 36th Meeting of Standing Committee on Power System Planning in Western
Region held on 29.08.2013, LILO of one ckt of Aurangabad (PG) – Padghe 765kV
D/c at Pune GIS in lieu of Kolhapur-Padghe (PG) 765kV D/c one ckt via Pune GIS
was agreed as System Strengthening Schemes in WR for transfer of power to SR
from IPPs in Chhattisgarh.
5
7.2
Subsequently, in 32nd meeting of Empowered Committee on Transmission held on
17.01.2014, the above scheme was agreed to be implemented through TBCB under
System Strengthening for IPPs in Chhattisgarh and other Generation Projects
in Western Region. Presently the process of transfer of SPV is under progress.
As per the route survey carried out by the BPC for LILO of one ckt of Aurangabad
(PG) – Padghe (PG) 765kV D/c line at Pune GIS, the route length for LILO portion
comes out to be 67KM approximately. Originally the length of Aurangabad (PG) –
Padghe (PG) 765kV D/c line was about 285KM and 2x240MVAR line reactors along
with 2x1200Ohm NGR are available at both ends of Aurangabad – Padghe 765kV
D/c line. After LILO at Pune GIS, the length of modified sections i.e. Aurangabad
(PG) – Pune GIS 765kV line would be about 254KM and Pune GIS – Padghe (PG)
would be about 165KM. Accordingly, in order to have proper reactive compensation,
1x240MVAR line reactor along with 1200 Ohms is proposed at Pune GIS for
Aurangabad (PG) – Pune GIS 765kV line.
8.0
Replacement of Overhead conductor with UG cable on GETCO portion of
KAPP 1&2 – VAPI/Balitha (GETCO) 220kV D/c line.
8.1
Transmission System for KAPP 1 & 2 consists of KAPP 1&2 – Vapi/Balitha (GETCO)
220kV D/c Single ACSR Zebra line - 117KM which is an ISTS line and tariff of the
same is claimed by POWERGRID. A certain portion of above line towards the end of
Vapi (GETCO) substation is owned and maintained by GETCO. GETCO portion of
KAPP 1&2 – Vapi / Balitha (GETCO) 220kV D/C line is terminated in different D/C
towers upto the point from which POWERGRID portion starts. In order to release the
adjoining land for developing various residential schemes at Vapi / Balitha, GETCO
proposed to replace existing 220kV conductor with approx. 255mtr underground
220kV XLPE cable from their portion of KAPP 1&2 – Vapi 220kV ckt 2 from 220kV
Vapi / Balitha S/s. The cost of the modification work would be borne by M/s GETCO.
8.2
POWERGRID/ GETCO may present the scheme details.

POWERGRID has proposed to convert the fixed line reactors into switchable line
reactors so that they may be utilized as Bus Reactors, as and when needed to
improve voltage profile. Further, NGR removal/bypassing may be considered for the
above lines for successful auto-reclose. DOV Studies for the above lines have been
carried out and no DOV phenomenon has been observed in absence of the line
reactor.
POWERGRID may present the DOV studies and members may deliberate.

10.1.5 Sub-synchronous resonance due to HVDC: Sub-synchronous resonance at
HVDC Mundra-Mohindergarh at Mundra end has been observed in the past. The
Sub-synchronous study performed was based on the data of 660 MW units of
Mundra and there were no lines between Varsana and Bhachau. In the past the subsynchronous resonance has led to Bipole tripping and loss of generation at APL
during which SSR protection has acted but could not damp the sub-synchronous
resonance. As with the commissioning of 400 kV Bhachau-Varsana circuit, the
electrical distance between CGPL UMPP and Mundra Generation complex has
reduced significantly. Earlier any commutation fault on HVDC side is also felt only by
the Mundra generating complex and CGPL is located at large electrical distance.
However as of now both are experiencing the electrical jerks from these faults. In
view of this there is a chance that Sub-synchronous resonance is going to get
affected with the both generating complex. So, a sub-synchronous resonance study
of HVDC Mundra Mohindergarh considering 330/660 MW units of Mundra and 830
MW units of CGPL may kindly be done in order to take remedial action for damping
of the SSR.

14 Connectivity System for NTPC-SAIL Power Co. Ltd. (2x250MW, Phase III, Stage-II)
14.1
NTPC-SAIL Power Co (P) Ltd (NSPCL) had applied for connectivity of its 500MW
generation project in Chhattisgarh as per the CERC regulation, 2009. The
application was initially discussed in 16th meeting of WR Constituents regarding
Connectivity / Open Access Applications held on 09.05.2012 wherein connectivity
was proposed to be granted through Bus extension of existing 400kV NSPCL
switchyard.
In the meeting, it was decided to defer the grant of connectivity till next meeting in
view of the very little progress with respect to fuel and environmental clearance
made by the generation project. Applicant was requested to keep the status of the
generating project informed so that their application may be processed accordingly.
After that no updates were received from generation developer.
14.2 The application was again discussed in 21st meeting of WR Constituents regarding
Connectivity / Open Access Applications held on 17.07.2015. NSPCL informed that
they are anticipating the COD of generation unit by 2018. He also informed that most
of the power would go to SAIL plant, hence only bus extension is sufficient for said
connectivity. Accordingly, it was decided that intimation for grant of connectivity with
bus extension of existing 400kV NSPCL switchyard to be issued. NSPCL to sign
connectivity agreement within 30 days, otherwise the grant of connectivity shall be
cancelled.

Aurangabad (PG) substation and Aurangabad (PG) - Aurangabad I (Waluj) 400 kV inter
connection was the limiting factor for import of power in Maharastra from ISTS. In the
meeting, it was agreed that MSETCL proposal of shifting Aurangabad I (Waluj) – Pune
(PG) 400kV D/C line from 400kV Aurangabad I (Waluj) to 765/400kV Aurangabad (PG)
would be studied jointly by CEA, CTU, WRLDC and MSETCL.
The peak demand met by Maharastra in August 2015 is 18447 MW. Accordingly, load
flow studies was carried out by taking recent load flow file from WRLDC for a demand of
18,445 MW in Maharashtra. In the studies intrastate generation of Maharashtra of
11893.4 MW (Tirora – 2418MW, Koyna – 552.8, Jaigad – 1000MW, Amravati- 750 MW)
and import of about 6500 MW from ISTS has been considered.

Load flow study has been carried out to see the impact of the following transmission
schemes which are already under implementation by PGCIL/MSETCL on the power flows
in Aurangabad I (Waluj) - Aurangabad (PG) 400 kV interconnection:
(i)
LILO of 400kV D/C lines Parli – Pune (PG) at Pune (GIS) - already
commissioned.
(ii)
2 nos. of 400 kV bays at Dhule (MSETCL) for termination of Dhule (Sterlite) –
Dhule (MSETCL) 400 kV D/C line.
(iii) LILO of both circuits of Aurangabad I (Waluj) – Pune (PG) at Pune(GIS) ) by
September 2015
(iv) Aurangabad (PG) – Sholapur D/C 765kV line by December 2015
(v)
Aurangabad (PG) – Padghe 765 kV D/C line by March 2016
(vi) Aurangabad (PG) – Boisar D/C 400 kV line by March 2016
(vii) Bableshwar – Kudus 400kV D/C line by March 2016.
(viii) LILO of one circuit of Aurangabad (PG) – Padghe 765 kV D/C line at Pune
(GIS) – project under bidding stage.
The load flow results are attached as annexures. The results are summarized in the table
given below. From the load flow analysis it is clearly evident that with the commissioning
of the above mentioned elements loading on 400kV Aurangabad (Waluj) – Aurangabad
(PG) D/C line has been reduced from 2460MW to 706MW and Aurangabad (Waluj) –
Aurangabad (PG) D/C line would not be constraint for import of power from Maharashtra.

400/220KV substation could be through bus extension or through 220kV lines as
the case may be.
(ii) 400kV (Quad) connectivity between the new substation at Xeldem and Mapusa to
take care of any N-1-1 contingencies involving outage of any one 400kV infeed to
Goa.
In the meeting alternative LILO of Narendra – Kolhapur 765kv D/C line charged at 400kV
level was suggested by POWER GRID. It was decided that alternatives would be studied
jointly by CEA and CTU. Accordingly the following alternatives for feeding Xeldam 400 kV
substation has been studied including the alternative proposed in the 38th SCM:

The observations based on analysis of the results are:
• OPTION: 1 is best possible alternative for providing ISTS feed to Goa system since
it has successfully relieved loading on existing 220kV network as well as 400kV
network which is feeding power to Goa system
• For implementation of Option 1 two no. of 400 kV bays would be required at
Narendra (existing) 400/220 kV substation. In case of space constraints GIS bay
may be provided. If no space is available then option 6 or option 7 could be
implemented which are equally good as option1.
• In the all the eight alternatives, the 400 kV lines to Mapusa/ Xeldam has to cross
the Western Ghats section.
• In the corridor through which the Narendra(existing)-Xeldam 400 kV D/C line would
pass, there are already existing Ambewadi – Xeldam/Ponda 220 kV D/C line and
Supa-Ponda 110 kV D/C line. Ambewadi – Xeldam/Ponda 220 kV D/C line is
functional whereas the Supa-Ponda 110 kV D/C line is not in use. These lines are
maintained and operated in their respective geographical areas by Goa and
Karnataka respectively. In case of difficulty in getting RoW for implementation of
Narendra (existing)-Xeldam 400 kV D/C line, the RoW of the existing Supa-Ponda
110 kV D/C line could be used.
• Option5 i.e, LILO of one ckt. of Narendra(New)- Kolhapur(PG) 400 kV D/C line at
Xeldam which was suggested in the 38th SCM is not a suitable alternative as there
is uneven loading on the 400 kV circuits feeding power to Xeldam ( 540 on one ckt
and 82 MW on other ckt.) . Also Narendra(New)- Kolhapur(PG) is a 765 kV D/C line
which in present scenario is being operated at 400 kV level and in future when this
line would be operated at 765 kV voltage level , the Xeldam 400 kV along with the
feeding lines also needs to be upgraded to 765 kV level.

Minutes of the meeting held on 02.09.2015 on issue related to connectivity
of 2x 660 MW Generation Project of M/s Lanco Vidarbha Thermal Power
Ltd. (LVTPL)
A meeting to discuss the issues related to connectivity of 2x660 MW generation
project of M/s Lanco Vidarbha Thermal Power Limited (LVTPL) was taken by
Member (Power System), CEA on 2nd September 2015 at CEA, New Delhi. The
list of participants is enclosed at Annexure-I.
1. CEA informed that the connectivity arrangement, LILO of Seoni - Wardha
765 kV S/C line at LVTPL TPS, for 2x660 MW generation project of M/s
LVTPL was agreed in the 12th meeting of WR Constituents regarding
Connecitivity / Open Access Applications held on 08-07-2010.
Subsequently, in the 21st meeting of WR Constituents regarding Connectivity
/ Open Access Applications held on 17-07-2015, the connectivity
arrangement for generation project of M/s LVTPL was revised to LVTPL TPS
– Warora pool 765kV D/C line and M/s LVTPL was requested to confirm the
time frame by which connectivity line was required, so that suitable action
may be initiated for implementation of the line through Tariff Based
Competitive Bidding route. M/s LVTPL vide their letter dated 27th August,
2015 has requested for continuation of the earlier connectivity granted i.e.
LILO of Seoni - Wardha 765 kV S/C line at LVTPL TPS.
2. M/s LVTPL informed that
i) They are developing 2X660 MW thermal power project near Mandva
village in Wardha district of Maharashtra. Based on the connectivity
arrangement agreed earlier (i.e., LILO of Seoni - Wardha 765 kV S/C line
at LVTPL TPS), the switchyard equipment has already been ordered and
most of the equipment have been received and the work at their
switchyard end is going on.
ii) The work on the project got hampered for 34 months due to enormous
delay in obtaining the Environmental Clearance (EC). After receipt of EC
in August 2014, approval of the project lenders was obtained in March
2015 for cost overrun funding with a revised completion schedule of May
2017 (for Unit 1) and September 2017(for Unit 2).
iii) The synchronization of Unit 1 is targeted by November 2016, as such the
start-up power would be required for the project by August, 2016. The
connectivity line is required before August 2016. Any change in the
connectivity arrangement already agreed, at this stage, would lead to
schedule mismatch which would be unacceptable to Project Lenders and
would jeopardize the progress work taken up with great difficulty.
iv) Therefore, the connectivity arrangement agreed earlier (i.e., LILO of
Seoni-Wardha 765 kV S/C line at LVTPL TPS) needs to be retained for
the project to achieve it target timelines.
3. CTU informed that the LILO connectivity was agreed in year 2010 and
significant developments have taken place in the transmission system in last
5 years and Seoni - Wardha 765 kV line has become part of the trunk
transmission corridor in WR. LILO interconnection would result into
unbalance power flow in the trunk corridor besides increasing the fault level
at Wardha 765 kV bus, which has already reached near design level of 40
kA. Further, a new 765/400 kV Warora pooling station is under
implementation as a part of transmission system associated with Gadarwara
STPS (2x800MW) of M/s NTPC Ltd., which is scheduled for commissioning
by November 2017. In view of this the connectivity has been revised to
LVTPL TPS – Warora Pool 765kV DC line.
4. POSOCO said that they are not in favour of LILO of trunk lines at generating
stations. They have already filed petition in CERC wherein it has been
prayed that Central Transmission Utility (CTU) should be directed to review
all connectivity granted to ensure that the CEA Standards are followed and
stop granting connectivity through interim LILO arrangement and the
connectivity already granted through interim LILO arrangements may be
shifted to final arrangements. The hearing has been completed and the order
is reserved.
5. CEA and CTU stated that
i) M/s LVTPL has applied only for connectivity. The power to the
beneficiaries of the project on firm basis cannot be transferred without
taking LTA in ISTS and till date M/s LVTPL has not applied for LTA. On
receipt of LTA application, the additional transmission system
strengthening requirement would be identified and LTA would be effective
after implementation of the identified transmission system strengthening.
ii) The connectivity line as agreed in the 21st LTA meeting held on
17.07.2015, LVTPL TPS – Warora pool 765kV DC line, would be
adequate to take care of the evacuation requirements till Warora pool. The
additional transmission system strengthening requirements, if any, based
on LTA application of M/s LVTPL would be only beyond Warora pool.
iii) The implementation of the LVTPL TPS – Warora pool 765kV DC line
would be taken though TBCB route wherein, the completion time of the
line in matching time frame of the generation project would be specified. In
case of mismatch (transmission line along with Warora pooling station not
coming in matching time frame of generation project), interim arrangement
would be evolved.
iv) For taking up the implementation of the line through TBCB route
a) M/s LVTPL needs to confirm the commissioning schedule of the
generation project.
b) As per CERC sharing regulations, transmission charges are payable
by beneficiaries only after the commercial operation of the generator.
Till then, it is the responsibility of M/s LVTPL to pay the transmission
charges.
c) M/s LVTPL needs to sign connectivity agreement and submit requisite
Bank Guarantee.
The issue was further deliberated and M/s LVTPL
above requirements so that the connectivity line
765kV DC line) could be put as agenda in the
meeting on transmission, scheduled to be
implementation of the scheme though TBCB route.
was requested to confirm the
(LVTPL TPS – Warora pool
35th Empowered Committee
held on 14.09.2015, for
M/s LVTPL stated that they would come back on the issues after discussion with
their management.
The meeting ended with thanks to the chair.
